7. © 2006 Open Grid Forum 7 Grid User Network Interface Draft Objectives Define, describe and provide extensions to existing UNI standardization documents (OIF, IETF) required to support Support/Propagate Grid service requirements/functionalities over GMPLS Support Broader range of transport networks Optical Transport Network Sub-wavelength switching (e.g. OBS, OPS) Interface Grid with Network Resource Provisioning Systems Interface with Grid Users/Applications/Resources via Web Services and take into consideration a number of OGF standardised languages of describing jobs and resources. Support of Service-Oriented architectures Functionalities and requirements OGF OASIS

8. © 2006 Open Grid Forum 8 Grid User Network Interface Extend the idea of UNI that is a service interface between a standard user and network for connection establishment and think more of a => Grid service interface that links any type of Grid End Point through Middleware with a broadened Grid Network Service Provisioning System. Grid User Grid Application Grid Middleware GMPLSNRPS Grid Resource OBS/OPS

17. © 2006 Open Grid Forum 17 GUNI Capabilities Exchange/Transaction of service and agreement related events/messages over heterogeneous Grid-aware GMPLS transport layer such as: Job info transaction Resource info transaction/process Provide Grid Security Services … Flexible bandwidth allocation Allocation of bandwidth with different grades of granularity. Automatic and timely light-path setup Traffic classification, grooming, shaping and transmission entity construction Fault detection, protection and restoration Security

18. © 2006 Open Grid Forum 18 Proposed Functionalities up to now

19. © 2006 Open Grid Forum 19 Functionalities I Grid Service Invocation : Control plane/Layering architecture: The GUNI must provide a general and open definition in order to support different architectural models. However, the information exchanged northbound and southbound is architecture dependant. Overlay model: In this model the Grid user sees the optical network topology as a black box and Grid user protocols are separated from network protocols. Under this model, the optical network provides a set of well-defined services to clients. Peer model: network acts like a single collection of devices including user and single protocol runs by both user and optical nodes for the optical path placement and setup. (e.g. Unified Control Plane layer integrating Middleware and GMPLS)

20. © 2006 Open Grid Forum 20 Functionalities II Optical transport : SONET/SDH Ethernet (1GE, 10GE,e.g. OIF UNI v.2.0) Optical Transport Network Switching transport format OBS OPS Multicast Grid Network Service Provisioning On-demand: Capability to provision Grid resources (network + grid) just in time having into account actual available resources. In-advance: Capability to provision Grid network resources by reserving them in future time slots.

21. © 2006 Open Grid Forum 21 Functionalities III User required features Job request Job submission as Described by JSDL Job manipulation Job scheduling: transparent and efficient access to remote and geographically distributed resources. User requested job priority Application classification Allocation of resources based on percentages User specifiable resource requirements Concurrency limit on the numbers of jobs a user is allowed to run User report (management reporting) should be available for a variety of time frames and should contain the following information: Number of request submitted, succeeded, failed, canceled Total CPU time used Total wall clock time used Total bytes transferred

22. © 2006 Open Grid Forum 22 Functionalities IV Resource required features Resource capabilities: applications need to explicitly specify their resources Resource availability Resource monitoring Resource reporting (management reporting) Usage reports to understand which users and/or organizations are using a particular resource or group of resources Utilization reports that show the degree to which a resource or group of resources are approaching their capacity and should contain the following for each grid resource, sorted by resource ID Checkpointing and Job Migration Grid Force Deletion Protection restoration in case of Grid or/and Network failure Escalation Security Authentication, Confidentiality, Data integrity

23. © 2006 Open Grid Forum 23 Call for participation Contribution on views and technical ideas from other research people and major projects as well as industrial groups are more than welcome. The structure of the document is open for discussion The level of technicality and approach First step General description of GUNI architecture, functionalities, requirements Possible Follow-up More detailed description on objects, messages It is open for new ideas that can be integrated with existing ones or stand alone on separate chapters/paragraphs.
